EYEGLAS S SPRING RETAINER Filed June 18, 1928 Symantec Patented Feb. 10, 1931 PATENT FFECE ALFRED LOUIS ROLLING, OF SAN FRANCISCO, CALIFORNIA EYEGLASS-SPRING RETAINER Application led June 18, 1928. Serial No. 286,139.

This invention relates to an eyeglass spring retainer, and one object is to produce a hook having a transverse V shaped gripping surface on the end piece of the bridge of an eyeglass which Will prevent the spring from being accidentally slipped out of place and thereby reducing the pressure on the nose piece so the eyeglass will not stay on the nose. A t Will he understood by those skilled in the art that `with common forms of spiral spring nose piece eyeglasses that the users are continually having trouble with them by reason of the fact that in Wipino' the glasses, the user often slips the end of the spring out of its place, and then the nose piece *it-hout retaining the glasses in place becomes useless, until the spring has been reset.

With the present invention the end piece of the bridge is so shaped as to provide a hook having a e shaped gripping surface under Which one end of the spring is piaced, and the hook vriil not allow the spring to escape if the apparatus has been at all Well made.

@ther objects of the invention Will be ape5 parent as the description proceeds.

fin i Abodiment of the invention is shown in the accompanying drawings in Which the saine reference numeral is applied to the saine portion throughout the several figures 30 of the drawings of which there may be Inodiications. y

Figure 1 is a front elevation of an eyeglass with this hook applied thereto, I

Figure 2 is an enlarged view of the hook with the spring and glass removed, and

Figure 3 is an end view of the bridge end showing the hook projecting transversely of `the glass, and having a J shaped gripping surface.

The numerals 1 and 2 indicate the eyeglasses vvhich are connected together by the bridge 8, screivs at i and 5 connecting the straps 6 and 7 to the end pieces 8 and 9. rlhe noseguards 10 11 are provided with the arms 12 and 13 which are pivoted on the post 111- adjacent each end piece.

rthe two posts 14 are pivot points for the nose guards, and they also serve as vretainers for the spiral springs 15 and 16, screvvs 17 and 18 in the top of the posts acting to hold the springs down on the nose.

Each end piece has a hook 20 under which the end of the nose guard spring is placed, said hook projecting transversely of the glass and l aving a 1! shaped gripping surface holding the end against accidental displacenient at all times.

vwhen the spring end is engaged under the hooks 20, 21 it is alniost impossible to accidentally disengage said springs from the hooi; and prevent the proper operation of the nose guard. The transversely placed and downwardly shaped projection on the end piece having the post that carries the spring so close that the end thereof passes under the hook by such a short span that it is dii'licult for anything to catch on and dislodge it.

Having thus described my invention, what 1 desire to secure by Letters Patent of 'the' United States is as follows, but modifications may be inside in carrying out the invention as shown in the drawings and in the above particularly described forni thereof, Within the purviewrv f the annexed claims.

1. An eye glass comprising a bridge, an end piece projecting from said bridge, a nose guard pivotally mounted on the bridge, a

spiral spring having one end secured to the nose piece, and the other end of the spring l bearing upon the end piece, and a hook projecting transversely on the end piece and having a V shaped gripping surface to retain the spring in its proper position.

2. An eye glass spring retainer comprising a bridge having end pieces and straps, vertical posts on said bridge adj acent the end piece, nose guares pivoted on said posts, downwardly and transversely projecting hooks having V shaped under-gripping surfaces on said end pieces, coil springs mounted on said posts, the loiver end of said spring bearing on said nose guards, the upper end sprung down to engage said a shaped gripping surfaces.

In testimony whereof I have hereunto set .my hand this 11th dav of June, A. D. 1928.
